Hello,
I'm starting a tank for Diodon holocanthus, but I fear it would feel lonely being the only fish and my fish store can order a great variety of other puffers and I was wondering if I could add some Ganthigaster species.
Do you think they would get along?
I have had D. holocanthus before with some other fish but not Ganthigasters.
Also, do you have recommendations for relatively small algae eater I could put with them?

Thanks, that was a great article!
Previously I have kept all of those species that were mentioned that can be kept as a group, and some that live alone, and one breeding pair.
So I'll choose some algae eating companion that won't be competing of food with the D. holocanthus, then.
